Update: I tried the wine today. First I mixed a splash of each in a glass and tasted it. The nose is actually better than I was expecting, but the body was still pretty thin and the taste was excessively tart. Oak is not making much of an appearance yet, so I think I'll give it a few more weeks at least.
After the taste, I added a few drops of glycerine and some wine conditioner to see if things improved. They did, markedly. The tartness was no longer evident, and while I probably overdid it on conditioner, the wine had become much more balanced. It was a far cry from the big, bold cabs that I tend to like, but it actually tasted remarkably like some of the inoffensive commercial reds that I've encountered. And it certainly tasted much "fuller" than the standard recipe.
I'll update again in a few weeks when the oak has made more of an appearance.
